The forward is closing in on a £45million move to north London from Nottingham Forest on deadline day.
Johnson had been linked with Chelsea and Brentford, but Spurs will soon sign him as their ninth arrival of the summer.
He will also be their most expensive acquisition of the window as he surpasses the £40m fee paid for James Maddison.
A move to Spurs will likely see him line up alongside Richarlison as Ange Postecoglou hopes to deliver silverware to the club.
However, Johnson and his soon-to-be Brazilian teammate have previously shared a feisty encounter on the pitch.
